Abstract:

As a green natural biopolymer, chitosan-based polymeric surfactants have attracted more and more attention because of their excellent properties. The common methods for preparation of macromolecular surfactants modified by chitosan were summarized, including alkylation, quaternization, carboxymethylation and acylation. The modification conditions and the properties of products were summarized. The applications and potential applications of chitosan-modified polymeric surfactants in the fields of food, medicine and cosmetics were introduced. The rules in the preparation of chitosan-modified polymeric surfactants were summarized and the development direction was prospected.

Key words: chitosan modification, natural surfactant, alkylated chitosan, surface activity
